Active ingredients: how and why evidence-based alcohol behavioral treatment interventions work.

This article summarizes the proceedings of a symposium that was organized and chaired by Richard Longabaugh and presented at the 2004 Research Society on Alcoholism meeting in Vancouver, British Columbia, Canada. The aim of the presentation was to focus on evidence for the active ingredients of behavioral therapies for patients with alcohol use disorders. Dennis M. Donovan, PhD, reviewed evidence for the active ingredients of cognitive behavioral therapy. Barbara S. McCrady, PhD, presented a conceptual model for mechanisms of change in alcohol behavior couples therapy and reviewed evidence for this model. J. Scott Tonigan, PhD, presented data testing three hypothesized mechanisms of change in twelve-step facilitation treatment. Mitchell P. Karno, PhD, presented therapy process data that tested whether matching therapist behaviors to client attribute across three therapies affected drinking outcomes. Jon Morgenstern served as discussant.
